Do you have proposals?
I use Inkscape for maps...though admittedly the main decision factor was "I'm already used to it", so YMMV.
Another quick way which does not even require you to draw something is to snap a picture of a fire escape plan from a building you know, that also makes it easier for you to visualize the building. If it's your workplace, you can also ask the safety guy if he has that plan as a PDF.
